SEEET-ROUFING.

Specification of Application filed May 9,

and State of Colorado, have invented a new i and useful Sheet-Roofing,of which the following is a specification.

-My invention relates to a new type of flexible asphaltumshingle-appearing sheet roofing.

And the objects of my invention are:

First, to provide individual sheets or strips of asphaltum roofingmaterial of a width corresponding to the length of an ordinary woodenshingle, their weather exposed surface being provided with raised ribmembers that are spaced at distancesapart corresponding to the generalwidth of individual wooden shingles, which ribs are positioned along thelength of the sheets of asphaltum thus giving to the sheets theappearance of wooden shingles.

Second, to provide long, narrow sheets or strips of asphaltum roofingmaterial that represent shingles, which shingle representing sheets maybe of any predetermined length, and which shingle representing sheets orstrips are manufactured and shipped in rolls of shingle length, andwhich rolls are arranged to be laid in successive shingle laying andoverlapping form, arranged and adapted to the same weather exposure andunderlapping surfaces as is used with wooden shingles.

Third, to provide a simple and quick laying type of sheet asphaltumroofing which forms a continuous row of individually appearing shingledroofing that presents to the eye of observers when laid the appearanceof a Wooden shingled roof. v

I attain these objects by the form of roof ing illustrated in theaccompanying drawings in which:

Figure 1 is a perspective view of a portion of a shingle-appearing stripconstructed in accordance with my invention.

Fig. 2 is a view illustrating the manner of applying the shingle stripsto the roof of a house.

Fig. 3 is an edge view of two overlapplng shingle strips.-

Fig. 4 is an enlarged sectional view on the line 4-4 of Fig. 1.

showing a portion of a strip having relatively wide ribs, and

Fig. 6 is a view of a fragment of a strip showing the narrow form ofrib.

Similar letters of reference refer to similar parts throughout theseveral views. 7

Referring to the drawings, the numeral 1, designates a sheet or a stripof my flexible asphaltum shingle representing roof sheeting material,which may be especially made 1,

up in the exact lengths required for the roof it is to be laid on, orthe strips may be cut from a long roll of the shingle sheeting.

Each sheet or strip 1, of my shingle representing roofing is preferablymade nine inches wide and it contains at intervals of preferably eightinches apart throughout its entire length a raised rib member 2, whichvaries in width from about one-fourth of an inch to about three-quartersof an inch in width, the wider rib members being more easily seen onhigh buildings, while the narrower ribs are of ample width for low andmedium height buildings. These raised rib members extend from the loweredge 3, of the shingle sheeting across its width for a distance ofpreferably four inches, which distance is the preferred width of theweather exposed surface 4:, of the strip of shingle representing roofsheeting.

As my continuous shingle representing strips of roofing are nine incheswide and as four inches of it is exposed to the weather, the remainingfive inches represents the underlapping portion 5, of the shingle strip,and of this five inches about one inch forms an underlapping edge 6,which lies against the roof boards 7, and is overlapped five inches bythe second shingle strip 1 above it, as shown at 8, in Fig. 2, and isoverlapped about one inch by the lower end 9, of the third shingle strip1 above it, andmy continuous shingle representing strips of flexibleasphaltum are laid in this progressive overlapping order from the loweredge of a roof to its upper edge which arrangement forms a three-plythickness or three layers of the shingle representing roofing stripsalong the upper edge portion 12, of the weather exposed part of eachshingle member and along each longitudinally extending layer of the roofsheeting strips across the roof of a building.

The upper underlapping five inch portion in i 5, of eachshinglerepresenting strips 1, of roof sheeting, 18 provided with'raisedrib members 2, the same as the lower four nch weather exposed portion 4,and the raised ribs 2 of the underlapping portion 5, of the a longshingle strip 1, are all also positioned at eight inches apart, by whichis meant that they'are eight inches apart from center to center of theribs, which is also the distance apart of the lower ribs 2, on the lowerweather exposed portion 4, of the sh1ngle* strips. These raised membersare designed to represent to the eye the cracksior narrow spaces thatoccur between wooden shingles when laid, and also that become morepronounced? through shrinkage of the wooden shin les after they arelaid.

y invention contemplates any way of representing on the surface of theshingle strips 1, of my asphaltum roofing material, such form and shapeand character of raised rib members spaced at what is consideredstandard' width of wood shingles that will represent to the eye of anobserver from the street, a roof that has been shingled with individualshingles, and I have represented both a wide rib 2, in Fig. 5, and anarrow rib 2 in Fig 6.

My inventlon contemplates shingle representing ribs of any*width, andthey are formed by subjecting the strips of asphaltum to a rollingpressure, which is applied by feeding the strips through suitably formedrolls which forces the ribs outwardly from the weather exposed side ofthese shingle wide strips into a" narrow rib-like portion of j theasphaltum, which pressed out rib-members project preferably about aneighth of an inch above the surface of all of the rest of the width andlength of these shingle strips of asphaltum roofing material, which isrolled out fiat and smooth. and of even thickness throughout theirentire length and width except where their raised ribs are formed.

In pressing out and thus projecting outwardly these ribs from thesurface of the shingle forming strips 1, a recess 10, of correspondingdepth and width is formed in the under side surfaces of each rib exactlyopposite to them as these ribs are formed by a swaging pressure movementthat forces a raised rib shaped member ofthe shingle strip bodily atright angles to the underside surface 11, of the shingle sheets, whichforms the recess and at the same time forms the raised or projecting rib2, on the upper and they are positioned centrall between the ribs 2, ofthe weather exposed ower art of the shingle strips, and they extend romthe upper edge 12, of the shingle strips, down to even with the u perends of the lower ribs 2, which is de ned by a dotted line 13, and theseupper shallow depth ribs have been especially desi nod to act as guideribs to enable the shing e laying workman to plainly see that eachshingle strip must be laid so that these shallower ribs will standcentrally between the ribs 2, on the same strip and in line with theribs 2 on the shingle below; that'is, that they will la and extendupward from the center 0 the eight inch space between the lower ribs incentrally positioned offset and alternate order of arrangement; andin'laying the shingle strips the lower edges of each stri laid is placedwith its lower edge throug out its length 5 across the length ofthe'roll close up againstthe upper ends of the lower ribs 2, which wouldbe along the dotted line 13, as the upper ends of the ribs 2, form aguide line across the roof that the lower edge of each shingle stripthat is to be laid on the one already laid is to be placed against, and

when this is done the recesses in the under side of the lower portion ofeach shingle sheet as it is laid fits down over the shallower ribs 2 ofthe upper part 5, of the shingle strip that has been already laid on theroof. I

The operation of laying my improved long, thin and flexible strips ofshingle rep- 100 resenting flexible asphaltum roofing material on pitchor inclined roofs is as follows and is as illustrated in Fig. 2:

A strip of the shingle representing roofmg asphaltum is laid eitherfully across a 105 roof lengthwise of it or as far across as desired atits lower or eaves edge, and is nailed to the roof boards;'but the loweredge of this first shingle strip is bent down over the eaves board 3 andis extended far 110 enough below its lower edge to form a water drlpplngedge, and this overlapping edge ofthls lower or first strip is thennailed to the eaves strip 3. A second sheet is then laid fiatwise alsoalongthe length of the 115 roof parallel to the first strip andoverlapplng the upper edge portion of it five inches;

the workman adjusting the lower edge of the second to lay against theupper edges of the raised ribs 2, of the first shingle strip 2 laterallysothat the ribs recesses on its under side will fit over the shallowribs on the upper'portion of the first and lower strip that has beennailed to the roof, which allows the fiat under side surface of theupper 1 5 part of the second shingle strip to lie flat down against thelower shingle strip below it, and as it is soft and flexible it iseasily pressed down perfectly fiat and smooth over the upper part of thestrip underneath by the workman who then nails ittightly to the shinglestrip below it. A third shingle stri is then laid to overlap the upperpart 0 the second shingle strip and is nailed to it and to the roof, asshown and the lower edge portion of the thir shingle strip can be nailedto the second shingle strip and also the one inch wide upper edgeportion 6,- of the first shingle laid on-the roof which projects upunder about an inch of the lower edge of the third shingle strip,consequentlyithere are three thicknesses of the shingle strips along thewhole length of the roof at this triple overlapping portion of them. Theshingle 4 strips are then laid in successive order to the ridge of theroof across its width or height.

My invention provides a thoroughly practical, durable and quickly andcheaply laid shingle representing roofing of an asphaltum compositionthat has been in constant use for roofings for buildings of all kindsfor a good many years, a practical application of which was invented andpatented by me in Patent No. 1,148,647, issued August a, 1915.

Having described my inyention what I claim as new and desire to secureby Letters Patent is:
